The content management server 11 and the POS management server 12 are set in a head office (hereinafter sometimes referred to as the office) of a convenience store (hereinafter sometimes referred to as the store). The POS terminal 13 and the charging station 14 are set in the store. It is noted that the POS management server 12 and the POS terminal 13 may be a server and a terminal already existing respectively in the office and the store.

Next, at business model utilizing the battery utilizing system 1 (from the introduction to the utilization of the battery utilizing system 1) will be described with reference to FIG. 1.

First, the office purchases the battery 10, the content management server 11 and the charging station 14 included in the battery utilizing system 1 at a system manufacturer for a given price (S1). Next, the office rents the battery 10 and the charging station 14 purchased in S1 to the store (S2).

When a user possessing the cellular phone 15 goes to the store, the user buys the battery 10, which has been charged and stores a given coupon or a given application program previously transmitted from the content management server 11 set in the office, for a given price at the store (S3). Then, the user inserts the battery 10 bought in S3 into the cellular phone 15 possessed by the user as shown in FIG. 1 (S4). Thus, the application program stored in the battery 10 is automatically activated, so as to display the coupon stored in the battery 10 on a screen of the cellular phone 15 (S5).

When the user buys merchandise by using the coupon at the store, the user holds the screen of the cellular phone 15 displaying the coupon over a reader connected to the POS terminal 13, so as to pay a price calculated by discounting a reduced price shown in the coupon from the proper price of the merchandise in cash or electronic money (S6).

When the battery 10 bought in S3 has been run out and cannot be used for the cellular phone 15, the user goes to the store and exchanges the battery 10 with another charged battery 10 placed in the charging station 14 free of charge (S7). In exchanging the battery 10, the charging station 14 may transfer a coupon stored in the battery 10 brought by the user to the charged battery 10 to be given to the user so as to take over the coupon.

The POS terminal 13 transmits, at a given timing, POS information on actual results of sales, marketing and the like of merchandise as well as coupon use history information on coupon use history (coupon use results) to the POS management server 12 via the network 16 (S8). Next, the POS management server 12 receives the POS information and the coupon use history information transmitted in S8 and determines a coupon to be newly stored in the battery 10 by analyzing these pieces of information in cooperation with the content management server 11, and the determined coupon is transmitted to the charging station 14 via the network 16 (S9).

When the charging station 14 determines that the life of a battery 10 placed therein has expired, it transmits a battery life alert for informing the expiration to the content management server 11 via the network 16 (S10).

Next, the cellular phone 15 places the specified coupon/advertisement file as a favorite by setting a flag on the coupon/advertisement file (SC9).

In this manner, a coupon/advertisement file to be displayed can be changed corresponding to the time basis or corresponding to the gender or age of a user, and therefore, the frequency of visiting the store or the like can be increased. Furthermore, since a coupon/advertisement file to be displayed can be restricted by the time or date, coupon/advertisement files to be displayed can be effectively narrowed without a user selecting a desired coupon/advertisement file from a large number of coupon/advertisement files through a complicated operation. In this manner, a coupon/advertisement file with a valid period expired or not started can be automatically excluded, and a coupon/advertisement file invalid at the current time can be prevented from being displayed. For example, a coupon/advertisement file valid only after the evening is not displayed in the morning.

Furthermore, since a coupon/advertisement file to be displayed can be changed corresponding to the age bracket, display of an inappropriate coupon/advertisement file (such as display of discount information of alcohol to minors) can be effectively prevented. Moreover, since a coupon/advertisement file to be displayed can be changed corresponding to the POS information, a coupon/advertisement can be strategically displayed. Specifically, a coupon/advertisement file concerned with discount information can be appropriately displayed corresponding to, for example, the stock state (the total stock), the remaining days before a sell-by date or a promotion period of each piece of merchandise, and therefore, undesirable stock (stock of multiple stores within a given district or stock of each store) can be effectively reduced.

Furthermore, since a coupon/advertisement file valid at the current time is extracted from all coupon/advertisement files stored in the battery 10 to be displayed and the rest are not be displayed, the frequency of visiting the store or the like can be kept. Specifically, since information on the future (such as information valid tomorrow) can be set not to be displayed, a user can be made to feel like visiting the store immediately. Moreover, when a user visits the store for exchanging the battery 10, purchase of other merchandise may be expected.

In addition, when advertisements of a variety of companies are stored in the battery 10, an advertisement of a corresponding company can be discriminated (extracted) on the basis of the personal information such as the age and gender to be displayed on the cellular phone 15, and therefore, advertisements can be effectively delivered, resulting in achieving a sales effect expected by advertisers. Also, the personal information such as the gender and age are only registered in the cellular phone 15 and not transmitted to the side of the store, which is preferred from the viewpoint of privacy protection.

Furthermore, since a coupon/advertisement file is guaranteed by a provider of the battery 10, there is no need to perform an operation in danger of virus infection (such as an access to the Web) on the side of the cellular phone 15, and hence, a user can use the battery utilizing system 1 without concern. In particular, since the majority of the elderly are currently uncomfortable using functions other than the e-mail function, such people are preferred as users of the battery utilizing system 1.

Then, a user operates the key-input I/F 15 k of the cellular phone 15 for directing the cellular phone 15 to take steps in the purchase of the music content.

The cellular phone 15 takes the steps in the purchase of the music content directed by the user by accessing a web site selling the music content through packet transmission (SH5). When a music content stored in the battery 10 is not purchased, the battery 10 may automatically delete the music content after the trial period has expired.

The cellular phone 15 acquires the music content whose purchase has been completed in SH5 from the battery 10 (and also executes a process for permanently validating the music content), and stores the content in the integrated memory 15 c (SH6).

In this manner, since a plurality of musical pieces or the like can be stored in the battery 10, a user can obtain a musical piece or the like inexpensively through download of a short period of time differently from the current principal utilization form where a musical piece or the like is obtained through cellular phone packet transmission expensively through download of a long period of time. Furthermore, when the process for permanently validating a music content or the like is performed through a cellular phone web site, the music content or the like can be acquired with small data communication traffic, and as a result, the load on the wireless communication infrastructure can be reduced and the communication cost can be reduced.

Moreover, validation/invalidation of trial of a music content can be controlled on the basis of the time information obtained by the cellular phone 15 itself. Furthermore, since the number of trials of a music content can be grasped through the operation with the cellular phone 15, the validation/invalidation of trial of the music content can be controlled on the basis of the number. In addition, in purchasing the battery 10 or thereafter, the personal information such as the gender and age can be input or input information can be changed. Also, when a music content of an up-and-coming artist is stored in the battery 10 for delivery, not only the utilization of the battery 10 but also the sales promotion of the music can be realized. Alternatively advertisement information can be randomly delivered, or a music content corresponding to the personal information such as the gender and age can be downloaded in exchanging the battery 10.

[3-2-3. Partial Browsing and Purchase of a Book Content]

4. Alternative Embodiments

In a museum or an aquarium, a battery 10 storing contents concerned with exhibits put on display such as paintings and animals is lent at the entrance, and thus, the contents can be browsed without consuming the battery of the cellular phone 15.

Alternatively, in a theme park or the like, a battery 10 storing contents concerned with guide information on the theme park and events held on a current data is lent at the entrance, and thus, the contents can be browsed without consuming the electricity of the cellular phone 15. As a result, the cellular phone 15 can be used for taking pictures or the like in the theme park without concern for the battery consumption.

For example, the cellular phone 15 acquires location information on the location of the cellular phone 15, reads a content permitted to be output at the location on the basis of the acquired location information and output permission range information previously set with respect to each content (information on a permitted range of outputting the content), and displays the read content on the display I/F 15 h. In this manner, in facilities such as a museum, an aquarium or a theme park, when a user possessing the cellular phone 15 connected to the battery 10 storing contents concerned with exhibits and events of the facilities comes close to a display place of each exhibit or a place for an event (for example, a given range including a display place or an event place), he/she can confirm, via the portable terminal 15, information on the exhibit displayed in that place or the event held in that place.

Alternatively, in the case where the battery 10 storing contents is lent in a museum, an aquarium, a theme park or the like, as compared with the conventional case where a PDA storing contents is lent, the device to be lent is inexpensive and small, and hence, the rent can be suppressed. Therefore, when the income derived from posting of advertisements can be secured, the rent can be free of charge.

Furthermore, since a browsing available period of a content can be limited in the battery utilizing system 1, even when a significant content is included in the lent battery 10, there is no need to withdraw the battery 10. When the income derived from posting of advertisements can be secured, there is no need to return the lent battery 10 and the battery 10 can be distributed free of charge. When the battery 10 can be distributed free of charge, there is no need to take steps in lending the battery 10, and therefore, a queue conventionally formed when lending can be avoided.

Alternatively, the battery 10 can store not only a still image but also a speech or a dynamic image. Also, since it can be determined by a built-in application of the cellular phone 15 whether or not a content stored in the battery 10 has been browsed, a gaming element like Stamp Rally can be incorporated by utilizing information on the determination result.
